Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

Oxygen is the key substance for life and one of the most abundant elements in the Earth. However, it’s still unknown whether oxygen is present and in which form in the inner core with extreme high ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Earth's core might be layered like an onion, according to a new study that looked at the anomalous nature of waved in the ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

(CNN) — Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth's crust through its core. The very center of the planet, a solid ball of iron and nickel ...

Earth's inner core is likely a weird composition of superheated elements making it both liquid and solid at the same time, a study has suggested. The extreme temperatures and pressures found at the ...

The diamond anvil cell used in this experiment. (A) Symmetric Diamond Anvil Cell, (B) Schematic diagram of a diamond anvil. The orange circle is the area corresponding to (C, D) (C) Image of the top ...

Earth’s core isn’t just a boring, featureless ball of metal, it turns out. A recent study used seismic waves from earthquakes to make a 3D model of the center of our planet, and the researchers ...
